to misuse, accidental damage, modification, or improper installation procedures.
Furthermore, this warranty does not cover any product that has had the serial number
altered, defaced, or removed. This warranty shall be the sole and exclusive remedy to the
original purchaser. In no event shall REACH be liable for incidental or consequential
damages of any kind (property or economic damages inclusive) arising from the sale or use
of this equipment. REACH is not liable for any claim made by a third party or made by the

1. Introduction
1.1. Overview
The SLCD+ controller provides complete Graphical User Interface for embedded systems
using QVGA or smaller LCD panels. Using the SLCD is simply the quickest way to
generate a user interface without a lot of graphical programming. It has a small size to fit in
space-constrained applications.
1.2. Features
Drives either active (TFT) and passive (STN) displays
Touch controller (4 wire resistive) on board
Beeper for audible touch feedback and alarms
3" by 4.5" size, only 0.2" thick
Low power (40mA typical at 5V)
RS232 or TTL level interface up to 115200 baud
User downloadable bitmaps with RLE compression (4MB of flash memory)
Backlight enable and brightness control
Reasonable cost
Supports either landscape or portrait mode display (firmware option)
Can be modified for specific OEM requirements
RoHS Compliant as of Jan 1, 2007
SLCD+ Controller Manual V1.1 8/14/2009 Page 8

1.3. Dimensions - Rev G board
Figure 1: SLCD+ Rev A Board Physical Dimensions (inches)
SLCD+ Controller Manual V1.1 8/14/2009 Page 9

1.4. Electrical Characteristics
The SLCD+ board takes in two voltages. One is simply passed though to the backlight
inverter, and is typically either 5V or 12V. The SLCD+ itself requires 5V. For other
hardware options, contact Reach Technology Inc.
The SLCD+ is designed for panels with VCC of 3.3V and built-in DC-DC converters and
therefore do not need high positive or negative voltages. A list of compatible panels in
provided in Appendix A.
Typical current draw is as follows:
State mA
No panel attached, beeper quiet 40
No panel attached, beeper active 80
In general, the panel backlight power requirements dominate the power budget.
1.5. Environmental
The standard SLCD+ controller is rated for commercial temperature operation of 0 to 70ºC.
An industrial grade -40 to 85ºC version is available as a special order. Note that most LCD
panels have a limited operating temperature range of -20 to 70ºC.
1.6. Panel support
The SLCD+ is factory programmed with panel configuration-specific firmware that
includes panel type, orientation (landscape / portrait), backlight inverter control polarity,
and touch panel orientation. Panel types include passive color (CSTN), or active matrix
(TFT). Different commands and connection options may not apply depending on the
firmware programmed on a given board. For example, there is contrast adjustment for
passive panels but not for TFT panels. Please note that both landscape and portrait display
modes cannot be supported by the same firmware; that is, the panel orientation cannot be
changed “on-the-fly”. The firmware is in-system-upgradable to support different
requirements and version upgrades.
1.7. Upgrade options
Reach has an upgrade to the SLCD+ that can provide more performance and supports
larger panels. To provide for such an upgrade, the four mounting holes that are symmetric
with respect to the board outline are recommended for use.
SLCD+ Controller Manual V1.1 8/14/2009 Page 10

2. Configuration Guide
2.1. Power
Note: The standard configuration is for 5V power input and 3.3V panel power. For other
configurations, please contact Reach.
2.2. Serial
The SLCD+ has four serial ports. Any can be used to send commands to the board. The
ports and their characteristics are as follows:
Port Description
COM0 Typically RS-232; remove a resistor for 3.3V CMOS logic level
COM1 3.3V CMOS logic only. Control signal (RTS) for RS485 driver enable
COM2 RS232 only
COM4 3.3V or 5V logic level I/O (on-board voltage translator)
COM0 is primarily used for RS232 communication, while COM1 supports 3.3V CMOS
level signaling with RTS handshaking for an external transceiver such as RS485.
By default, serial communications is 115200 baud, 8 data bits, no parity, with 1 stop bit,
with receive flow control via XON / XOFF. This can be changed by using a “power-on
macro” which is described in the companion manual SLCDx Software Reference.
2.3. TFT Panel Orientation
The SLCD+ can support QVGA TFT panels with standard 33 pin flat flex pinouts. Some
panels also have signals for display orientation, called Right/Left and Up/Down. These
signals are controlled via the firmware using the “*orient” command. Refer to the SLCDx
Software Reference.
2.4. Grounding
In order for the touch screen to work properly with a panel that has a CCFL backlight, the
panel metal frame must be grounded to the SLCD+ ground. All SLCD+ mounting holes are
connected to SLCD+ ground.

4. System Overview
4.1. General SLCD+ Controller
The SCLD acts as a "smart terminal" and is generally connected to a host processor that
implements the desired Graphical User Interface (GUI) by issuing commands to the
SLCD+ and processing button press responses from the SLCD+. In this manual, the term
"host" is used to describe the device connected to the SLCD+.
Please refer to the SLCDx Software Reference Manual for more detail.
4.2. Overview - SLCD+ Evaluation Kits
The SCLD+ is available in an evaluation kit form, and also as a complete enclosed unit. In
the kit or enclosure, it comes pre-loaded with bitmaps and macros that implement a demo
if the unit is powered on with the communications port looped back transmit to receive.
This loopback is via external plug in the case of the enclosed unit, or via a jumper on the
"PowerCom" board in the case of the unenclosed kit.
The SLCD+ evaluation kit comes with hardware and firmware options loaded for the
specific panel supported by the kit. It also includes a two-port DB9 interface board that
makes it easier to connect to external host systems. One port can be used to download
bitmaps from a PC while the other connects to the "host" computer.
4.2.1. Getting Started
The SLCD+ kit as shipped contains a demo that allows you to verify its functionality. Plug
the supplied power supply into the barrel connector on the triangular shaped PowerCom 4
board. The display should light up and lead you through various touch-activated screens.
4.2.2. Connecting the kit to a PC
The kit should be connected to a PC so that the serial command interface can be
experimented with. This is a preliminary step before the unit is connected to the embedded
system that will control the display in the embedded system..PLEASE NOTE: In order
to communicate over the serial port, the Demo jumper JP1 on the triangular
PowerCom4 board must be removed. This jumper loops back transmit to receive on the
serial port and this is what tells the SLCD+ to run the demo.
SLCD+ Controller Manual V1.1 8/14/2009 Page 17

As shipped, the serial port is set to 115,200 baud, 8 bit, 1 start, 1 stop, no parity. There are
two DB9 connectors on the "PowerCom 4" board. Connect the PC using a straight through
cable to the DB9 marked "MAIN" (P1). A USB-to-serial adapter cable can also be used
and plugged directly into this connector. Note: the Belkin USB-serial adapter has
software compatibility issues and is not recommended; Reach recommends either
Prolific or FTDI chip based adapters.
Once connected, use RealTerm (preferred), HyperTerminal, or similar terminal emulator to
send and receive commands from the kit. HyperTerminal has limitations that can cause
problems; specifically, some versions cannot send the "escape" character. We recommend
RealTerm (shareware – Google “realterm” to download).
4.2.3. Developing the application GUI with an embedded controller as host
To develop the actual application, determine whether the host will interface via 3.3V or 5V
CMOS levels or RS232 levels. Then connect the host accordingly to either J6 (232) or J5
(CMOS levels). Then connect the PC to either J6 or J4 whichever is not used. This way
either the host or the PC can drive the SLCD+. Typically the PC is used to experiment and
determine what command is needed for a graphical interface, and to download new
bitmaps and macros without having to disconnect the embedded system.
How this dual port connection works is this: the SLCD+ has a non-volatile memory which
remembers which port is the “main” control port. This is selected via the *com0main or
*com1main command. The other port is then the aux port. When the aux port receives
three <return> characters in a row, it switches to become the main port. This way, the PC
can take control of the SLCD+ communications channel and send commands or download
new bitmaps. Use the reset button to simulate a power-on event which restores the main
port as the default control port, or use the *prevCons command.
